Title
(EN) SHAPED CHARGE EFFECT MEASUREMENT
(FR) MESURE DE L'EFFET D'UNE CHARGE FAÇONNÉE
Abstract
(EN)
A method includes determining a perforation tunnel geometry of a perforation tunnel in a solid sample, the perforation tunnel created by activating a shaped charge in proximity to the solid sample. The method also includes performing a first flow test on the solid sample and creating an analog aperture having an aperture geometry in a solid sample analog of the solid sample, wherein the aperture geometry and the perforation tunnel geometry satisfies a similarity threshold. The method also includes performing a second flow test on the solid sample analog and determining a shaped charge effect based on a comparison between a second flow test result and a first flow test result.

L'invention concerne un procédé consistant à déterminer une géométrie de tunnel de perforation d'un tunnel de perforation dans un échantillon solide, le tunnel de perforation étant créé par activation d'une charge façonnée à proximité de l'échantillon solide. Le procédé comprend également la réalisation d'un premier test d'écoulement sur l'échantillon solide et la création d'une ouverture analogue ayant une géométrie d'ouverture dans un échantillon solide analogue de l'échantillon solide, la géométrie d'ouverture et la géométrie de tunnel de perforation satisfaisant un seuil de similarité. Le procédé comprend également la réalisation d'un second test d'écoulement sur l'échantillon solide analogue et la détermination d'un effet de charge façonnée sur la base d'une comparaison entre un résultat de second test d'écoulement et un résultat de premier test d'écoulement.
